I am currently running a simulation in DPMFoam, openfoam version V2212. When i set the patch conditions in the kinematicCloudProperties to rebound i don't have an issue getting the solution to complete. When I change one of the patch conditions to stick I get the following issues:

I believe this to be a divergence issue although all the residuals i can view look good. My question is two parts:

1. When using the sticking patch type are there any additional conditions i need to include?
2. Are there any know issues with the particle stick model that impacts solution stability?

A snip of the code patch section looks like this

(

Wall_1
{
type escape;
}
Wall_2
{
type escape;
}
Wall_3
{
type stick;

e 0.001;
mu 0.001;
}
Inlet_1
{
type rebound;
e 0.97;
mu 0.09;
}
Inlet_2
{
type rebound;
e 0.97;
mu 0.09;
}
Inlet_3
{
type rebound;
e 0.97;
mu 0.09;
}
Outlet_1
{
type escape;
}
Outlet_2
{
type escape;
}

Hi Lenny, can you share your entire kinematicCloudProperties file? Can it be a problem with the large amount of particles attached to the walls?
